12 Claims.

This invention relates to an apparatus for cementing soles to shoe bottoms, and particularly to an apparatus of the type comprising a plurality of connected traveling sole-pressing elements, each having an inflatable pad and means for holding a lasted shoe against the pad, together with means for inflating each pad after a shoe has been loaded into the corresponding shoepressing element.

In an apparatus of this type the inflating of the individual inflatable pads is accomplished through the medium of an inflating device in the form of an air-supply chuck that is adapted to be momentarily coupled to an air valve with which each pad is provided, and one feature of my present invention relates to novel means for bringing the air-supply chuck and the air valve of each pad into registering alignment at the time that the pad is to be inflated.

In an apparatus of this type it is also customary to provide means for automatically deflating each pad as it approaches the loading position so that when the pad arrives at the loading position the shoe which is therein can be readily removed by the operator and replaced by another shoe having assembled therewith an outsole which is to be cemented thereto.

Another feature of the invention relates to a novel means for automatically deflating each pad as it approaches the loading position.

A still further feature of the invention relates to the construction of the portion of the shoepressing element which holds the shoe against the pad, and a further object of the invention is to provide a novel construction which facilitates the removing of a finished shoe from, the shoepressing element and loading another shoe thereinto to have the sole cemented thereto.

In order to give an understanding of the invention I have illustrated in the drawings a selected embodiment thereof which will now be described after which the novel features will be pointed out in the appended claims.

Fig. 10 is a fragmentary view showing the device for bringing the air-supply chuck and air valve into alignment.

As stated above, the device herein illustrated is of that type comprising a plurality of connected traveling sole-pressing elements, each having an inflatable pad and means for holding the shoe thereagainst, and in Fig. 1, i indicates a plurality of such sole-pressing units which are connected together in endless chain formation as indicated at 2. Each sole-pressing element is formed with a rigid box-like base portion 3 which is formed with a cavity or chamber 4 adapted to receive the inflatable pad 5. The pad herein shown is molded from rubber in the form of a seamless bag and the mouth of the bag is tightly closed or sealed by being clamped between two clamping bars 6 which are connected together by screws 1. If desired, the rubber bag 5 may be enclosed in an envelope 8 of leather or some other material which will withstand the wear occasioned by the sole-pressing operation.

Each shoe-pressing element l is provided with means for holding the lasted shoe against the pad and in the present embodiment of the invention such means is in the form of a yoke-shaped member 9 which extends from one end to the other of the base 3, and the arms I0 of which are pivotally connected to the ends of the base 3 as shown at II. This bar 9 is formed with a projection or rest E2 to engage the toe portion of the lasted shoe l3 and is also provided with a second projection it adapted to engage the heel portion of the last l5.

The operative position of the member 9 is the vertical position shown in Fig. 3 but when the pad is deflated the member 9 can be swung into an inclined position, thus removing it from the top of the lasted shoe thereby making it easy to remove the shoe from the shoe-pressing element.

The connected shoe-pressing elements I are shown as provided with guiding rolls l6 which operate in channel-shaped tracks l1 that are carried by the frame l8 of the machine, and, as stated above, the various shoe-pressing elements are connected together in endless chain formation. In the operation of the device these traveling sole-pressing elements have a continuous movement as distinguished from a stop-andgo movement.

Each inflatable pad is provided with an air valve I9 which depends therefrom and through which air is supplied to the pad to inflate it and is exhausted from the pad to deflate it. The air valve may have any suitable or usual construction, and as shown in Fig. 4 it comprises a valve casing 20 having a valve chamber 2| in which is received a valve 22 acted on by a spring 23 which tends normally to seat it against a valve seat 24. The valve has the stem 25 extending therefrom which normally projects beyond the valve casing.

The means for inflating each pad after a shoe has been loaded into the corresponding shoepressing element comprises an air-supply chuck 26 which is adapted to be coupled to the valve l 9. The air-supply chuck herein shown has the same construction as that illustrated in my co-pending application Serial No. 670,471, filed May 11, 1933, and it is provided with a valve chamber 21 which has communication with a supply pipe 28 leading to a source of compressed air supply, and it also has a valve 29 in said chamber which is normally held closed against a valve seat 39 by the air pressure in the air chamber 21. This airsupply chuck is formed with a recess or cavity 3| directly above the valve seat 30 and of a size to receive the end 'of the valve l9 of an inflatable pad. The chuck valve'29 has a winged extension 32 which is adapted to be engaged by the end of the valve 19 when the latter is inserted into the cavity 3| and which'is also adapted to engage the stem 25 of the valve 22. When, therefore, the chuck 26 is coupled to the pad valve element I9 both valves 29 and 22 will be open as shown in Fig. 4 so that air will be delivered from the supply pipe 28 into the inflatable pad thereby to inflate the latter.

This chuck 26 is mounted on the outer end of a swinging arm 33 that is pivotally mounted at the inner end at 34 to a bracket 35 carried by the frame IS. The outer end of the arm is sup ported on a track 36 in the form of a bracket which is secured to a portion of the frame l8, and for this purpose said arm 33 is provided near its outer end with a collar 31 carrying a roll 38 which rests on the track 36.

The chuck 26 normally occupies a position below the path of travel of the pad valves l9 and at one side of the vertical plane of said path. The coupling of the chuck to each valve IS involves first a movement of the chuck transversely of the path of travel of the valves to bring said chuck into the vertical plane in which the valves 19 travel, during which transverse movement of the chuck it is brought into registering alignment with the valve of the pad which is passing through the loading zone, and then raising said chuck from its lowered position shown in dotted lines in Fig. 4 into its inflating position in which it is coupled to the valve l9 as shown in full lines Fig. 4.

It will be remembered that the sole-pressing elements are moving continuously and this coupling of the chuck to any valve I9 occurs during the movement of the sole-pressing element.

This operation of moving the chuck 26 transversely to bring it into the plane of the path of 40 by a pin and slot connection 45. encircling the upper end of the rod 43 and contravel of the valves l9 and into registering alignment with the valve of the pad which is traveling through loading zone, and subsequently raising the chuck to couple it with said valve I9, is accomplished through the medium of a treadle 39 which is connected to and actuates an actuating lever 49 pivoted at 4| to a suitable stand or support 42,

The treadle 39 is shown as secured to the end of a vertically moving treadle rod 43 which extends through and is guided by apertures in brackets 44, the upper end of said rod 43 being pivotally connected to the outer end of the lever A spring 46 fined between the upper bracket 44 and a collar 41 on said rod normally holds the rod and treadle in elevated position shown in Fig. 3 with the stop collar 48, which is fast to the rod 43, engaging the under side of the upper bracket 44 and thus limiting the spring-impelled movement of said rod.

To provide for the lateral movement of the chuck 26 from its inoperative position shown in Fig. 3 to a position in the vertical plane of the path of travel of the valves I 9, I propose to make the arm 33 so that it can be extended in the direction of its length, Accordingly said arm embodies in its construction two members 49 and 50 which have a telescopic relation, the member 49 being a tubular member within which the member 50 telescopes. The member 56 carries at its outer end a head 5| having a seat 52 on which the chuck member 26 normally rests, said member having a depending stem 53 which extends through and is adapted to slide in an aperture 54 with which the head 5| is provided. The extensible section 50 of the arm 33 is so connected to the actuating lever 40 that when said lever is rocked counterclockwise by the depression of the treadle 39 said arm section 50 will be moved out Wardly into its extended position thereby carrying the chuck member 26 into the vertical plane of movement of the traveling valves l9. For this purpose I have provided a toggle device comprising two toggle members 55, 56 pivotally connected at 51, the member being pivoted at 53 to a collar 59 which is clamped to the arm section. 49, and the toggle member 56 being pivotally connected at its outer end to the upper end of a pin 60 which extends through the arm section 59 and operates in a slot 6| with which the tubular arm section 49 is provided. The toggle member 59 is connected by a link 62 to the actuating lever 40.

When the extensible arm 33 is in its normal contracted condition as shown in Fig. 3 the toggle device will be partially folded, this being the position of the parts when the actuating lever 49 is in its normal position. The depression of the treadle 39 will move the actuating lever 40 counter-clockwise and this movement of the lever opcrates through the link 62 to straighten the toggle, thereby moving the arm member 50 outwardly into the position shown in Fig. 5 and thereby bringing the chuck member 26 into the vertical plane of the path of travel of the valve I9.

In order to bring the chuck'and the valve I9 into registering alignment at the time that the chuck 26 is moved outwardly into said vertical plane, I have provided a chuck-aligning device 63 which is carried by an upright arm 64 rising from the arm section 59. This chuck-aligning device 63 is in the form of a plate having the two converging valve-engaging'edges 65 which terminate The inflating mechanism above described is situated in the loading zone, that is, the zone in which each sole-pressing element is traveling at the time that the operator loads a shoe into it. Inasmuch as the shoe-pressing elements are moving continuously through the loading zone the operator has to use his judgment as to the proper time to depress the treadle. The chuck-aligning member 63 has suflicient dimension in the direction of the travel of the valves l9 so that a considerable time element will be required for each valve to pass the chuck-aligning member 63. When each sole-pressing element arrives within the loading zone the valve l9 thereof will be located at some point opposite the edge of the chuck-aligning member 63, and when the operator depresses the treadle 39 and moves the chuck 26 and chuck-aligning member 63 transversely the valve i9 will be engaged either by one of the inclined valve-engaging edges 65 or by the seat portion 66. If the valve is engaged by one of the inclined valve-engaging edges 65 as shown in Fig. 10 the pressure of the chuck-aligning member against the valve will cause the arm to swing about its pivot and the valve to slide down the inclined edge 65 into the seat 66. This seat 66 is positioned directly over the cavity 3! in the chuck, and when the valve is seated in the seat 66 the chuck and the valve will be in registering alignment, and said chuck can be coupled to the valve by being moved upwardly from the dotted to the full line position in Fig, 4. This coupling movement of the chuck which brings the chuck into inflating position is given to it by the lever 40. The outer end 57 of the lever is formed with an extended flat surface 68 and the stem 53 of the chuck has at its lower end a head 69 carrying a roll H! which is adapted to be engaged by the surface 68 of the lever during the final portion of its operative movement, and thereby the chuck is raised into its inflating relation with the valve.

It will thus be seen that during the initial operative movement of the lever 45 the arm 33 is extended to bring the chuck into the vertical plane of movement of the valve l9 and simultaneously the chuck and the chuck-aligning member 63 cooperate to bring the valve and chuck into registering alignment, and during the final movement of the lever do the chuck is raised into its inflating position with relation to the valve shown in full lines Fig. 4.

To provide for the continued swinging movement of the lever 5 after the toggle has been straightened and the valve 59 has been seated in the seat portion E56 of the chuck-aligning member, I propose to make the toggle member 56 capable of having a telescoping action. This member is formed with an outer tubular section I! and an inner section 12 which telescopes within the tubular member H, the inner memher having a pin 13 operating in a slot i i with which the tubular member is provided and which allows the telescoping action but prevents separation of the two sections H and '12. A spring '25 is located within the tubular member 13 and bears against the inner end of the section 12, said spring normally holding the two members in their extended relation shown in Fig. 3.

The spring 75 is sufiiciently strong so that it will resist any telescoping action of the two members 'ii, 12 until the arm 33 has been extended and the valve 59 has been brought into the seat 66 of the chuck-aligning member.

When this occurs further extending movement of the arm is prevented and as the lever 40 continues its operative movement the spring I5 will yield to allow the member E2 to telescope within the tubular member 13 as shown in Fig. 5. In operating the device the operator, who stands within the loading zone, will load each shoepressing element i with an assembled shoe and outer sole as said press arrives at said loading zone, it being understood that the pad is deflated at this time. As soon as the shoe-pressing element has thus been loaded the operator will depress the treadle 39, thereby first bringing the chuck and the valve of the loaded shoe-pressing element into registering alignment, and then raising the chuck member into their coupling arrangement with said valve. This results in inflating the pad, an operation which takes place during the traveling movement of the shoe-pressing element. The pivotal mounting for the arm 33 and the telescopic structure of said arm not only provides for thus bringing the chuck into inflating relation with the valve but also permits the chuck to partake of the straight-line movement of the valve during the inflating operation. When the pad is fully inflated the operator releases the treadle and the spring 56 raises the latter and moves the lever A 9 clockwise into the position shown in Fig. 3. During the first part of this clockwise movement the chuck 25 drops from the full to the dotted line position, Fig. 4, and during continued clockwise movement of said lever the toggle device 55, 56 is folded and the arm 33 is contracted, thereby moving the chuck 26 into its normal position at one side of the plane of travel of the valve. The arm 33 is shown as having two centering springs 76 connected thereto by which it is normally held in central position, said springs operating to return the arm to this position after it has released the valve.

I have also provided herein means for automatically deflating each pad just before it arrives at the loading zone, thus releasing the shoe therein so that it can be removed by the operator. The deflating device herein shown comprises an arm ll pivotally mounted at T8 and carrying at its outer end a block 19 which is pivoted to the arm at 89 to permit vertical swinging movement of said block. This block 79 has a roller 8! which rides on a track 82, the latter being provided with a raised cam portion 83. Secured to the outer end of the arm 'i'l is a bracket 8 having at its upper end a laterally extending valve-engaging flange 85, the latter being situated in position to be engaged by each valve l9 during its traveling movement. The arm H is acted on by a spring 85 which normally holds it in its retracted position shown in Fig. 8 with the block resting against a stop Bl.

As each sole-pressing element I approaches the loading zone the valve !9 thereof will engage the flange 85 so that during further forward traveling movement of the sole-pressing element the arm Tl will be swung to the right from the dotted line position to the full line position in Fig. 9.

At the time that the valve l9 engages the flange 85 the end of the valve stem 25 will be situated directly over the block 79, and as said arm is swung toward the right, Fig. 8 by the forward movement of the valve E9 the block l9 will be moved over the hump 83. This will swing the block upwardly into the position shown in Fig. 1, thereby bringing it against the projecting end of the valve stem 25 and unseating the valve 22,

thereby allowing the air within" the pad to escape. As the valve I9 continues its forward movement the block 19 will pass off from the hump 83, and as said arm 11 moves slightly beyond the full line position in Fig. 9 the flange 85 will become disengaged from the valve, at which time the spring 85 will return the arm 85 and block I9 to its normal position with said block against said stop 81.

I have referred above to the construction of the sole-pressing element including the pivotally mounted yoke portion 9.

The machine herein shown is provided with means for automatically swinging the yoke 9 of each sole-pressing element from its upright position to its inoperative position just after the pad of said element has been deflated, thus carrying said yoke away from the shoe so that the operation of removing the shoe from the pad is facilitated. The machin is provided with a bar 88 extending transversely of the direction of movement of the sole-pressing elements and situated to be engaged by the yoke 9 of each solepressing' element just after the pad thereof has been deflated. The engagement of this bar 88 with the yoke swings the yoke backwardly into its inoperative position as shown in Fig. 1.

The machine herein shown is also provided with means for returning the yoke 9 to its operative position just before the shoe-pressing element reaches the loading zone so that when the operator loads a shoe into said element the yoke 9 is in its operative position. For this purpose one of the arms ID of each yoke extends below I its pivotal point H and is provided with a cam portion 89 adapted to engage a plate 99 secured to one of the channel tracks 16. The engagement of the cam end 89 of the arm 99 with said plate causes the yoke 9 to be swung back into its operative position.
